Dave's Homemade Radios Crystal Schematic Selector Crystal Radio Schematic Selector Page. Hi friends. I suppose that some of you have noticed that I built a lot of crystal radios. Some might say that is an understatement. The selecting of a radio that you might want to make for yourself sometimes starts with looking at the schematic diagram. Crystal Radio Plans, Schematics, and Circuits Crystal radio plans, crystal radio circuits, crystal radio schematics are all right here. Crystal Radio Plans and Circuits and parts of books This section contains 174 articles at the present time (articles are numbered) Many articles have multiple plans! Information Donated In Part By The Following Persons ... Jim's Crystal Radio Page Hobby Tech This is the schematic diagram of a basic crystal set. The tuned circuits in a crystal radio are composed of a coil (inductor) and a capacitor, usually variable, to allow tuning the circuit to the desired frequency. How to Make Build a Crystal Radio | Circuit Diagram The crystal radio schematic shown below is very simple and one can easily build it in few minutes if all parts are available. The circuit require no power because it runs from the radio waves it receives Crystal Radio Circuits – Circuit Wiring Diagrams Simple Crystal Radio. The crystal radio gets its name from the galena crystal (lead sulfide) used to rectify the signals. A "cat’s whisker" wire contact was moved about the surface of the crystal until a diode junction was formed. The 1N34A germanium diode is the modern substitute for galena and most other germanium small signal diodes will ... Crystal Radio Circuits | Crystal Set Circuits ... In reality there may have been little to choose between the different crystal radio circuits, but each one optimised the performance in a different way. Basic crystal radio circuit. The circuits for crystal sets could be very simple. Some simply employed a tuned circuit, a crystal detector and a pair of headphones. Crystal Radios: Stay Tuned Crystal Sets Crystal Radio web site. Crystal radio plans, crystal radio circuits, crystal radio schematics are all right here. Sound powered headphones and how to use them on crystal radios.

Welcome to Dave Schmarder's 78 homemade crystal radio receiver projects with plans and schematic diagrams. I show very simple crystal sets, as well as high performance radios with holy grail parts. All crystal radio plans are shown. Others have made these into detector radio kits. Litz wire is often used. How to make a batteryless (crystal set) radio ... CRYSTAL SET. The simplest radio receiver, known as a Crystal Set, consists of nothing more than a coil, tuning capacitor, diode detector, and a pair of earphones. A typical circuit diagram for a Crystal Set Radio is given below where inductor or coil L1 is tuned by variable capacitor VC1 to the transmitter frequency. Crystal radio A crystal radio tuned to a strong local transmitter can be used as a power source for a second amplified receiver of a distant station that cannot be heard without amplification.: 122–123. There is a long history of unsuccessful attempts and unverified claims to recover the power in the carrier of the received signal itself.
